Dr. Andrey Molotnikov completed an undergraduate degree in Mathematics at Clausthal University of Technology in Germany in 2005. From 2006-2010 he studied at Monash University, Australia and was awarded a PhD in the field of computational materials science in October 2010. He subsequently undertook a post-doctoral research in the area of metallic composites and architectured / hybrid materials in ARC Centre for Light Metals, Melbourne from 2011-2014 before his appointment as a Lecturer in the Department of Materials Science and Engineering at Monash University, Australia in January 2015. Dr Andrey Molotnikov’s main research interest are:

  • Architectured materials
  • Computational Materials Science
  • Additive Manufacturing

His current research is focusing on combining the knowledge of these disciplines and using them as a foundation for a new approach to design of novel materials. Dr Molotnikov is part of the ARC Research Hub for Transforming Australia’s Manufacturing Industry through High Value Additive Manufacturing and leads several projects in this area. He was invited to present his work at numerous international conferences such as MRS Fall Meeting, Boston, USA (2015), NanoSPD6, Metz, France (2014), 2nd International School on Architectured Materials ARCHIMAT, Autrans, France (2014), Thermec’2013, Las Vegas, USA (2013). In 2016, Dr. Molotnikov was awarded France-Australia Science Innovation Collaboration Fellowship and he will spend time in France working on novel computational models to describe the mechanical behaviour of additively manufactured metal/polymer hybrid lattices.

Research Projects

Current projects

Powder bed additive manufacturing quality assurance

In the last five years, Additive Manufacturing (AM) has been globally recognised as potential manufacturing technology which could produce replacement parts on demand. Among several AM techniques Selective Laser Melting (SLM) is considered as the most advanced technology that provides the best geometrical tolerances as well as the mechanical and surface properties. However, the translation of this technology from a research environment to commercial products require the development of appropriate qualification protocols. Due to inconsistency of the produced parts, AM is only being applied to secondary or non-critical components, and to allow for use in critical load bearing applications each part must be either tested or inspected via limited NDI techniques at great expense. The proposed project seeks to overcome this limitation by applying a newly developed method of inspecting Powder Bed Fusion components in-process in real-time.

Innovative aluminium extrusion: increased productivity through simulation

This project will develop new approaches to increase productivity and competitiveness of the Australian aluminium extrusion industry. The innovative approach will use customised simulation software to optimise the design of extrusion dies, thereby substantially reducing the time and cost of developing new extrusion dies. It will similarly optimise the processing conditions for high quality extrusion, further contributing to cost reduction. The project will develop fundamental models of material deformation behaviour and damage accumulation that through computer simulation will contribute to increases in die life, and reduced scrap.

Transforming Australia's Manufacturing Industry through High Value Additive Manufacturing

This project will establish a world class, globally-linked and industry-focussed research hub to underpin the uptake of metal alloy based additive manufacturing (including 3D printing) in Australia. Its research will cover the issues that need to be resolved for success, including the effects of non-equilibrium solidification, process optimisation to achieve quality, consistency and repeatability, and new user-friendly design tools to realise the benefit of free-form manufacturing. Real components will be studied to give immediate impact. The hub will also train highly skilled people that will be needed for this growing industry.
